Re: Rules and authorizations to sell hookahs
you will need a business license, get the right code for tax filing for selling tobacco. im not to sure how the sale of tobacco stuff works, you may need to talk to the ATF (alcohol tobacco, firearms). gota card of course,
some places like to hassle hookah lounges and people that smoke hookahs but if you are in a large city or area with a large 18-20s crowd you should be ok.
for age its pretty much 18 everywhere except NY but or smoking inside it depends on state and jurisdiction and how the law is written
